Original application filed August 26, 1910, Serial No. 579,109. Renewed July 6, 1917, Serial No. 179,096. Divided and this application filed June 20, 1919. Serial No. 9410,1162.

To all whom it may concern:

I Be it known that 1, Enasros E. WINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Methods of Making Heels; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will ensingly in a form which alines the component lifts, usin the same form repeatedly after each ejection of a completed heel. An example of the type of machine employed in practising this method is shown in the atent to Eliphalet A. Tripp No. 1,056, 20, granted March 18, 1913, on an application filed June 9, 1909. It has also been proposed to provide a mechanical collecting device for the component lifts which picks the required number of lifts for a single heel successively from a series of stacks of lifts, one from each stack, and superposes them on each other, the entire operation being repeated for each heel that is built. An example of the type of machine employed in practising this method is shown in the patent to Charles W. Bowen No. 1,146,996, granted July 20, 1915, on an application filed August 16, 1907. It will be recognized by those skilled in the art that the prior methods of making heels are defective in that the requirement for completing one heelbefore another can be commenced reduces the output of the operative and. renders the entire operation slow and undesirable.

The present inventor has discovered a method of making heels by the use of which the material disadvantage just adverted to is overcome. Tn practising the novel method hereinafter described the operative is building not only one heel, but a plurality of heels simultaneously and the mode of operation is such that completed heels are being de- The object of the present invention is to improve upon present known methods of making heels by introducin into the buildmg process certain steps w iich provide for a slmultaneous building operation on a plurality of heels and thus, by eliminating the delay in starting successive operations, permit the operative to obtain a materially increased yield. In other words while, in building a six lift heel, for example, heretofore SIX handlings or deposits of the lifts were required and one six-lift heel was delivered only after the sixth handling, by the present method a plurality of six-lift heels are delivered in the same period of time, or for the same number of lift depositing. operations.

The practice of the method is facilitated by the use of some simple apparatus which will assist the operative in handling and depositing a series of lifts at a time, and will permit each such series of lifts to be advanced simultaneously beyond the stations of deposit and intermittentlythrough succeeding stations. As illustrative of one form of apparatus that may be employed a diagrammati representation is given of the essential features of the heel building machine illustrated and described in the inventors co-pending application filed August 26, 1910, Serial No. 579,109, renewed July 6, 1917, Serial No. 179,096. from which application the present application is a division. 7

The improved method will be explained with the assistance of the accompanying drawings in which:

Figure 1 is a skeleton view, in front elevation, of the building conveyor, employed in the machine of said parent application, for receiving and advancing the heel piles;

Fig. 2 is a skeleton view, in end elevation, of one of the sets of the lift handling pickers, employed in the machine of said parent ap- 'plication for transferring lifts from the source of supply to the conveyor, and

Fig. 3 is a diagram illustrative of the successive lift collecting steps required when using apparatus of the type illustrated in Figs. 1 and 2.

In practising the novel method the heel lifts are first separated into groups, or stacks if desired, which are arranged in a row to facilitate handling the lifts in series. Where i of the row and the smallest lift at the righthand end.

Since heels are to be produced in multiple, lifts must be taken from the groups and transferred to the building station in sno cessive series, the number of lifts in each series being equal to the number of heels which are to be built simultaneously. A convenient device for handling the. lifts has been found to be a picker which comprises a head having impaling devices which may be forced into the face of the lift, to hold it while being transferred, and then with drawn after the lift has been placed in proper position at a building station. A blank handling device of this type is illustrated in Figs. 68 and 69 of the patent to Emmet Horton, No. 760,791, granted May 24, 1904. In said parent application a plurality of pickers 2, of the general type of Horton picker, are mounted in a suitable frame for rotative movement about a shaft 4, each picker carrying a roller 6 which is engaged by one of a plurality of cams '8 on a cam shaft 10. The pickers are arranged in groups of three and the cams 8 are so designed that at the same moment of time each picker of a group is in a different angular position relative to the shaft 4, but the corresponding pickers of each group are in the same angular position. Thus, as illustrated in Fig. 2, the first picker of the series is at the building station 12 depositing a lift, the second picker is at the paste trough 14 dipping a lift, while the third picker is at one of the groups into which the lifts were originally divided, obtaining a lift. Pickers numbers four, five and six of the series are in the same relative positions as pickers numbers one, two and three, and similarly for the third group of three pickers, as is illustrated in Fig. 1.' A movement of the pickers toward and from the groups of lifts, paste trough and building station is secured by providing each picker with an eccentric strap 16 which surrounds an eccentric 18 on the shaft 4. Springs 20 maintain the cam rollers 6 in engagement with the cams 8.

p The detail of construction and mode of operation of all of this mechanism is fully de scribed in said parent application and for the purpose of the method herein set forth ready deposited thereon opposite the series of pickers which is next to deposit a series of lifts. Preferably the conveyer is in the form of a link belt which travels around sprockets '24 and is advanced step by step by a feed mechanism employing four-motion feed dogs like that disclosed in the patent to VVinkley No. 1,181,090, granted April 25, 1916, as a division from Patent No. 1,102,310,

granted July 7, 1914, on an application filed -August 26, 1910. In the present illustration the only part of the feed mechanism which is shown are the rolls 26, on the'pintles be tween the links, which are engaged by the .feed dogs. With this construction the links conveniently form separate building stat-ions for individual heels.

It will be observed that while there is a link of the horizontal run of the conveyer continually opposite each picker a lift is deposited only on every third link, due to theoperation of the pickers in groups ofthree. Therefore, while each link in the horizontal run is continually in lift receiving position, only three heels are being built simultaneously and, therefore, only each third link is employed as an individual building station. Since the building stations must be brought to the pickers successively the length of the feeding step of the conveyer is equal to but one third the distance between the individual building stations.

When using the illustrated apparatus pasted lifts are deposited on the building stations at each advance movement of the conveyer and the lifts are secured together during their collection in this manner. Heel manufacturers usually prefer to further secure together the lifts of each heel that is built, prior to the heel compressing operation. To this end a nailing mechanism 28, of usual construction, is provided at the end of the serles of pickers and, as each completed heel on the conveyer passes this point, a nail is driven thereby through the pile of lifts. The completed heels then pass downward between the conveyor and the guard 30 and are discharged at the oint where the conveyer again turns upwarc about the lower sprocket 24.

Reference to the diagram of Fig. 3 will give a clear conception of all the steps which 'may be used to build nine-lift heels in mulfl ll .tion by the pickers.

l neat-re are deposited by the first piclrer of each group of three pickers, on line 0; of the diagram, this series of lifts will be founddeposited on the 1st, lth and 7th building station which are opposite those piclrers. 0n line b, the conveyor having first been advanced one step, are found the series of lifts de posited by the second picker of each group collected With the first series of lifts on the 2nd, 5th and 8th building stations. the line 0, after the second advance step of the con veyer, are found the series of lifts deposited by the third picker of each grou on the 3rd, 6th and 9th buildin stations. n line cl the fourth handling of the lifts is shown, deposits of lifts as on line a being made, a new heel being started on the 1st building station, but the lifts already on the 4th and 7th stations collect additional lifts. Uri lines 6 and f the fifth and sixth handlings of the lifts are shown, the deposits being made by the same pickers as made the deposits on lines 7) and c. It should here be noted that the heels delivered to the mailer after the third and sixth handlings of the lifts by the pickers are incomplete, since, obviously, it required nine deposits to obtain the first complete heel. Finally, on line 5 the ninth handling of the lifts is shown, after deposits have been made on lines 9, it and a, lilre those previously described for lines 01, h and 0, and there is produced a complete nine-lift heel at the 9th building station While at the 6th station a similar heel is two-thirds complete and at the 3rd station one is one-third complete. it Will be observed that after the ninth handling of the lifts a completed heel is delivered at each third depositing operaf in Fig. l heels are shown in position as on line i of the diagram.

ll. Waste of heel material, after the third and sixth handling of the lifts, may be avoided by completing these two partially built heels by a hand. operation. in practice, however, this is taken care of by the operative who before beginning to deposit the successive series of lifts, will place a partially built heel comprised of three lifts from groups one to three on the el-th station, and a second partially built heel comprised of" six lifts from groups one to six on. the

7th station. Then, on commencing the so ries of deposits of lifts, starting with the picker group comprising the list, 4th and 7th piclrers and proceeding; as previously ex plained, the heel piles will, after the handling, appear as on line 9 and a com-- plete heel Will be delivered continuously at each third depositing operation as previously explained.

it "will be obvious that in using the apparatus disclosed in said parent application the groups of pickers may be duplicated to any desired eirtent and if the heel to be built does not retpiire as many lifts there are pickers, the extra pickers may be madeia operative b fastening them in the left-hand position 0' Fig. 2 or by removing the groups of lifts which su ply these piclre lln this connection particular attention is directed to the fact that in this application the term lift is used in an inclusive sense as defining any blanlr or layer of material useful in the formation of a heel pile from which a heel is ultimately produced, irrespective of the particular shape which the blanks may have when. they are first collected in the form of a heel pile.

Those skilled in the art will recognize that the apparatus illustrated is not the only apparatus which may be employed to assist in buildin heels in multiple When utilising the principle of depositing series of lifts on other series previously deposited, and refer ence should be had to the appended claims which define the true scope of the invention.

Having thus described the novel process and one mode of building heels when em ploying' its underlying principle, What is claimed as new is:

y 1. The method of building; heels in mul tiple which includes the steps of depositing a series of lifts in a row at separate stations; intermittently advancing said lifts simultaneously through succeeding stations in the row; depositing an additional series of lifts at each. period of rest; and applying paste to each series of lifts; whereby as the series of lifts are advanced additional lifts are simultaneously collected at each forward step, and heels of the required height as may be desired are produced in succession.

2; The method of building heels in mul tiple which includes the steps of depositing a series of lifts in a row at separate sta' tions; intermittently advancing said lifts simultaneously through succeeding stations in the row, the total number of stations be ing equal to the number of lifts required in the heel; depositing an additional series of lifts equal in number to the first series, at each period of rest; and applying paste to each series of lifts; whereby as the series of lifts are advanced additional lifts are fill ll ll till .llti

l. tl

i l o l l ti simultaneously collected at each forward 7 series of lifts in a roW at separate stations; intermittently advancing; said lifts simultaneously through succeeding stations in the row; depositing an additional series of lifts at each period of rest; whereby as the series of lifts are advanced additional lifts are simultaneously collected at each forward step, and heels of the required height as may be desired are produced in succession; and securing together the lifts of each heel.

' 4. The method of building heels in multiple which includes the steps of depositing a series of lifts at separated stations throughout a row of stations equal in number to the number of lifts required in the heel; intermittently advancing said lifts simultaneousl in steps equal to one-third the distance between said deposited lifts; and depositing an additional lift on each of the lifts thus advanced at each period of rest; whereby each successive series of lifts deposited is collected at a different series of stations on the lifts previously deposited are a heel pile is built after each third deposit of a series of lifts regardless of the number of lifts in the heel.

5. The method of building heels in multiple which includes the steps of repeatedly depositing different series of lifts in a row at different series of stations and intermittently advancing said deposited lifts simultaneously through succeeding stations in the row; the total number of stations being equal to the number of lifts required in the heel, and the number of lifts in each series being less than the total number of stations; whereby each successive series of lifts deposited is collected at a different series of the lifts have been advanced is equal to the number of lifts required in the heel.

6. The, method of building heels inmultiple by advancing lifts in series intermittently through a series of, stations equal innumber to the number of lifts required in the heel and successively adding additional lifts during their advance, which includes the steps of depositing a series of lifts at the 1st, 4th, 7th, etc., stations, then, after advancing said lifts to the 2nd, 5th, 8th, etc., stations depositing a second series of lifts thereon; then, after advancing said lifts to the 3rd, 6th,,9th, etc., stations depositing a third series of lifts thereon; and thereafter repeating the depositing operations at the series of stations named, and in order named, for each advance of the lifts to a new station until the lift deposited at the 1st station has been advanced through all the stations; whereby the first heel is produced after deposits of lifts equal in number to the number of stations and thereafter a heel is produced at each third deposit of lifts on those being advanced, regardless of the number of lifts in the heel.
